Abstract : The method of least square point matching is employed in the analysis of a shallow, circular cylindrical shell with a cutout. The cylinder may be infinite or semi-infinite, and the cutout is either circular or elliptic. For the ellipse the major axis can be oriented either parallel or perpendicular to the generator. In particular, two examples are presented: an infinite cylinder subjected to uniform axial tension, and a semi-infinite cylinder loaded at its edge by either a uniform bending moment or a transverse shear force. In both cases the minor axis of the elliptic cutout is parallel to the generator. The boundary of the perforation is free of tractions and supports. Numerical results are presented and show the effects of variations in: the hole size to cylinder curvature ratio; the eccentricity of the cutout; and for semi-infinite cylinders, the distance from the cutout to the edge.
